The cap which is shown in the drawings constitutes the preferred form or embodiment of the invention and serves as a medium for closing the filler pipe of an automobile gasoline tank or like container. The ller pipe is designated in the drawings by the reference numeral I3 and embodies at its upper or inlet end an internal annular ange I4, the outer portion of which extends at right angles to the pipe and the inner portion of which extends downwards. As shown in Figure 4, the flange I4 of the ller pipe is provided with a pair of diametrically opposite notches I5, and the parts of the inner portion of the downwardly extending inner portion of the iiange that extend between the notches have the bottom edges downwardly inclined in a clockwise direction and embody at the lower ends of such edges integral depending abutments I6. The cap comprises a disc-like body I1, a cup shaped carrier element I8, an attaching member I9, and key controlled locking means 20.

The body Il consi-sts of an inverted cup-shaped shell 2| and a crosswall 22 within the shell. Such shell is in the form of a sheet metal stamping and consists of a circular` concavo-convex top wall 23 and an integral annular depending skirt 24. The central or intermediate portion of the skirt is knurled as shown in Figure 1, in order that the body of the cap may be readily gripped and turned in connection with application to, and removal from, the ller pipe I3. The crosswall 22, like the shell 2|, is in the form of a sheet metal stamping. It is located beneath and in spaced relation with the top wall 23 of the shell, has a circular hole 25 in its central portion and embodies on the outer margin thereof an integral annular depending U-shaped flange 26. The hole 25 is arranged in truly concentric relation with the center of the concavo-convex top wall 23 of the shell 2|. The outer portion of the U-shaped ange 26 fits within the skirt 24 of the shell and is xedly secured thereto either by a press or drive t or by spot welding. When the cap is in its operative position the skirt 24 and the flange 26 surround the inlet end of the filler pipe I3, as shown in Figures 2 and 3. The diameter of the inner portion of the flange 2G is slightly greater than the diameter of the inlet end of the ller pipe in order that the cap when mounted on the ller pipe may be readily turned.

The cup-shaped carrier element I8 is preferably formed of stamped sheet metal. It is l0- cated within the central portion of the cap body I1 and comprises a circular bottom wall 21 and an integral upstanding cylindrical side wall 28. The upper end of the side wall 28 corresponds in diameter to, and is rotatably mounted in, the circular hole 25 in the central portion of the crosswall 22 and embodies an integral outwardly extending ilange 29 which overlies the hole dening portion of the crosswall and serves to prevent `downward displacement of the carrier element I8 with respect to the cap body Il.

The attaching member I9, like the cap parts heretofore described, is in the form of a sheet metal stamping. It consists of a at intermediate part 30 and a pair of coplanar, oppositely positioned, outwardly extending ngers 3|, and serves as a medium for releasably securing the cap in its operative position wherein, as shown in Figures 1 to 3, inclusive, the body I'| overlies and extends across the inlet end of the filler pipe I3. The flat intermediate part 3U of the attaching member I9 ts snugly within the cylindrical side wall 28 of the carrier element I8 and rests on the bottom wall 2l of the carrier element. The fingers 3| extend through and project beyond a pair of diametrically opposite notches 32 in the side wall 28 of the carrier element, as shown in the drawings. In applying the cap to the filler pipe I3 the body I1 is placed over the inlet end of the pipe and is then manipulated so as to bring the outer ends of the fingers 3| into registry with the notches I5 in the ller pipe ange I4. Thereafter the body is shifted downwards and then partially turned or rotated so as to bring the outer ends of the ngers into a position wherein they underlie the inclined bottom edges of the parts of the downwardly extending portion of the flange I4 that are disposed between the notches I5. When the fingers are in such position they serve to hold the cap in its operative position wherein it is in connected and sealed relation with the inlet end of the filler pipe. To remove the cap it is only necessary to turn or rotate it reversely until the fingers 3| of the attaching member I9 are in alignment with the notches I5. As soon as the ngers and notches are in alignment the cap may be removed by lifting it from the inlet end of the ller pipe. As hereinafter described the rotatably mounted carrier element I 8 is held against free turning relatively to the body I'I during manipulation of the cap into and out of its operative position. A ring shaped gasket 33 of cork or other compressible material surrounds the upper end of the cylindrical side wall 28 of the carrier element I8 and underlies the crosswall 22 of the cap body I'I. This gasket serves as a sealing medium and is clamped between the cross wall 22 and the outer portion of the flange I4 when the cap is in its operative position. The ngers 3| of the attaching member I9 underlie the gasket and operate to hold the latter in place around the cylindrical side wall of the carrier clermontv I3.

The key controlled looking means Il serves to lock the cap in its operative position and Gomprises a lock bolt 34 and a plugand barrel assembly 35. The lock bolt 34 is formed of stamped sheet metal and rests on the flat intermediate part 30 of the attaching member I9. It is longitudinally and horizontally slidable relatively to the carrier element I8 and embodies at one end thereof a dog 38 which extends through, and is slidably mounted in, a circumferential slot 31 in the cylindrical upstanding side wall 28 of the cupshaped carrier element I8. The slot 31 is disposed between the notches 32 and is so located or positioned that it is in registry with one of the notches I5 in the filler pipe flange I4 when .the cap is in its operative position. When the cap is in its operative position and the lock bolt `3.4.is shifted outwards, as shown in Figures 9 and 10, so las to project the dog 38 beyond the circumferential slot 31 and into the adjacent notch I5 the dog locks the carrier element against rotation relatively to the filler pipe and hence prevents removal of the cap. When the lock bolt is shifted inwards so as to eiect withdrawal of the dog 36 from the adjacent or opposite notch I5 the carrier element I8 is released so far as turning movement relatively to the filler pipe is concerned and hence it is possible by reverse rotative movement of the body to remove the cap from the ller pipe. The plug and barrel assembly 35 of the key controlled locking means 28 is centrally disposed in the space between the central portion of the top wall 23 of the cap shell 2I and the central portion of the locking bolt 34 and consists of a cylindrical plug 38 and a barrel 39. The plug and barrel extend vertically, as shown in Figures 2 and 3. The plug is rotatably mounted in the barrel 39 and has a longitudinal key slot 49 for a key 4I. It also has a longitudinal series of spring actuated plate tumblers 42 and these are mounted for transverse sliding movement relatively to the plug and are adapted when the key 4I is inserted into the key slot 4l) to be shifted into a position wherein z the ends thereof are flush with the outer periphery of the plug and when the key is removed from the key slot to be shifted by the springs that are associated therewith into a position wherein certain ends thereof are disposed in either of a pair of diametrically opposite, longitudinally extending slots 43 in the barrel 39. The upper end of the plug 33 registers with a circuit hole 44 in the central portion of the concave-convex top Wall 23 of the shell 2l in order that the upper end of the key slot 49 is accessible from the outside of the cap body I1. The plug 38 is adapted when the key 4I is inserted into the key slot 49 to rotate in connection with turning of the key back and forth throughout an arc of 180. The lower end of the plug is provided with a depending eccentrically disposed stud 45 and this is disposed within a transversely extending cam slot 46 in the central portion ofthe lock bolt 34 and forms an operative connection whereby the lock bolt is slid into and out of its locked position in response to back and forth turning of the plug 38 by way of the key 4I. The stud is so arranged that when said certain ends of the tumblers are in alignment or registry with one of the slots 43 in the barrel 33 it maintains the lock bolt in its locked position and when the plug is rotated by the key throughout an arc of 180 into a position wherein said certain ends of the tumblers are in alignment with the other slot 43 it slides the bolt into its retracted o1' it, together with the plate 4:1, serves to hold 4the look bolt liandthe eltteohing member laasainst upward-displacement with respect to the rotatable carrier element I8.

In addition to the parts heretofore mentioned the cap comprises means whereby when the look bolt is in its unlocked position the carrier element His held against free rotation relatively-to the .body to the end that the Cap as a AWhole ,may be applied to o r removed from the inlet end of the filler pipe and when the lock bolt is in its locked position the body and carrier element are released for free relative rotation and hence when the cap is in its operative position the body may not be utilized to turn the finger equipped attaching member I9 out Of connected relation .with the inwardly extending flange I4 of the iiller pipe I3. Such means comprises an arm 48 on the lock bolt 34 and an annular series of `pairs of up-struck stop-forming lugs 49 on the cross- -Wa11`22 of lthe cap lbody I1. The arm 48 is L- shaped and consists of a vertically extending part .5.0 ond a horizontally extending part 5I. The lower end of the vertically extending part v5I) ofthe arm 48 fits slidably in a notch 52 in the rlhg shaped plate 41 at the lower end of the b arrejl 39 and is formed integrally with the end of the lock bolt that is opposite the dog 36. The horizontally extending part 5I of the arm is formed integrally with, and projects outwards from, the upper end of the arm-part 59, extends through a notch 53 in the outwardly extending annular flange 29 at the upper end of thecylindrical Fside wall 28 of the c up shaped carrier element I8, and rests upon, and ts slidably against, the upper face of the crosswall 22 of the Cap body I1. The pairs of up-struck stopforn'iing lugs 49 are preferably three in number and are located adjacent the outer marginal portion of the crosswall 22. The length of the `horizontally extending part 5I of the arm 48 is such that when the lock bolt is in its unlocked position Vthe outer end of the part 59 is located vin the vpath of the lugs 49 and when the lock bolt is in its Vlocked position the outer end of the part 5I) is disposed -inwards of the path of the lugs. When the lock bolt is in its unlocked position the body I1 of the cap may be turned relatively to the carrier element until one of the lugs 49 strikes against the outer end of the horizontally eX- tendhg part 5I of the arm 48. At such time the lug coacts with the arm 48 so as to prevent further relative rotation of the body with respect to thencarrier element and thus the two are locked together in such manner that the cap maybe applied to, or removed from, the ller pipe in connection with turning or rotation of the A4body. When, after application of the cap to the ller pipe, the lock bolt 34 by proper manipulation of the key 4I is shifted-into its locked position the outer end of the horizontally extending part 5I of the arm 48 is disposed inwards of the path of the lugs `49, as previously pointed out, and hence the body I1 is permitted to turn or spin freely relatively yto the .carrier element I8 and hence cannot be utilized to disconnect the finger equipped attaching member I9 from the inwardly extending flange I4 at the upper or inlet end of the filler pipe I3. The arm 48 and the lugs 49 constitute or exemplify simple means whereby the body and carrier element are locked against free relative rotation when the lock bolt is in unlocked position and are released for free relative rotation or turning when the lock bolt is in its locked position.

When it is desired to apply the cap to the filler pipe the key 4| is inserted into the key slot 4U.v in the rotatable tumbler equipped plug 38 and is turned until such time as the lock bolt is shifted into its unlocked position. .As soon as the lock bolt is in its unlocked position the horizontally extending part I of the arm 48 coacts with one of the stop-forming lugs 49 to prevent free relative turning or rotation of the body I'I and the carrier element I8. After shift of the lock bolt into its unlocked position the cap is manipulated into place by placing the body over the inlet end of the ller pipe and then after insertion of the fingers 3| of the attaching member I9 through the notches I5 turning the cap in a clockwise direction so as to bring the outer ends of the fingers 3l under the inner downwardly extending portion of the flange I4. When the cap is turned to its fullest extent the gasket 33 is compressed between the crosswall 22 and the horizontally extending outer portion of the flange I4 and the circumferential slot 31 in the cylindrical side wall 2B of the carrier element I8 is in alignment or registry with one of the notches I5. After shift or manipulation of the cap into place the key 4I is turned throughout an arc of 180 in order to effect shift of the lock bolt 34 into its locked position wherein the dog 36 is in interlocked relation with the adjacent notch I5. After so turning the key the key is removed. As heretofore pointed out, shift of the lock bolt into its locked position results in inward shift of the horizontally extending part 5I of the arm 40 from the path of the stop-forming lugs 49 and results in the body Il of the cap being free to turn or spin relatively to the carrier element I8. Hence, when the cap -is in place while the lock bolt 34 is in its locked position the cap may not be removed from the filler pipe because of free turning of the body without attendant or corresponding angular displacement of the carrier element I8. When it is desired to remove the cap the key 4I is inserted into the key slot 48 in the plug of the plug and barrel assembly and is then turned so as to effect shift of the lock bolt 34 -into its unlocked position. When the lock bolt is so shifted the body and carrier element are held against free relative turning movement or rotation, as previously pointed out, and it is possible by turning the body in a counterclockwise direction to rotate the attaching member I9 so as to bring the fingers 3I into registry with the notches l5 in the flange I4 at the upper end of the filler pipe I3. As soon as the fingers 3I are in registry with the notches I5 the cap may be removed by shifting it upwards.

The herein described cap effectively and eiciently fulfills its intended purpose and may be manufactured at an extremely low and reasonable cost due to the specific design and construction of the parts thereof. By reason of the fact that the cap includes the arm 48 and the stopforming lugs 49 it is impossible to remove the cap when the lock bolt is in its locked position, except by use of the key 4I.

The invention is not to be understood as restricted to the details set forth since these may be modified within the scope of the appended claims without departing from the spirit and scope of the invention.
